    This is the case, but the important thing that David Schwartz said is that
    it does not rely on the time in a clock, but rather on the pretty much
    completely random skew between several independent clocks. Any particular
    oscillator will vary in speed semi-randomly, and if you compare multiple
    clocks you can get pretty random numbers.
